UNITED STATES PATENT OFFICE;

ERNEST FUCHS, OF BILLANCOURT, FRAINCE, ASSIGNOR TO LOUIS RENAULT, OF BILLANCOURT, FRANCE.

ELECTRIC HEADLIGHT.

Application filed January 16, 1915.

T all whom t may concern Be it known that I, ERNEST FUCHS, citizen of the French Republic, residing at Billancourt, Department of the Seine, France, have invented certain new and useful Improvements in Electric Headlights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to electric headlights for automobiles and other vehicles, and has for its object to provide an improved headlight in which the reflector and the lamp are mounted in a novel manner in the casing.

Another object of the invention is to so construct the headlight and its support that a circulation of air is maintained through the support and through the space between the reflector and the casing.

Among still other objects of the invention source of current in an improved manner.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a side elevation, partly in section, of a headlight constructed in accordance with the invention; and Fig. 2 is a front view, partly in section, of the structure shown in Fig. 1.

Referring to the drawing, it will be seen that the reflector is carried by an annular sleeve 2 and isfsecured thereto by means of a nut 3 which is screwed against a washer 4 that intervenes between the reflector 1 andv the nut. The sleeve 2 carries the lamp socket 5, through the rear wall of which passes the extremity of a bolt 6. The inner extremity of the bolt 6 is flanged as shown in the drawing, and the outer extremity is passed through the rear part of the outer casing 7 of the headlight. A nut 8 screwed upon the extremity of the bolt 6 serves to draw the reflector and the lamp socket, together with theV lamp, rearwardly toward the back of the casing 7 until the peripheral edge portion 9 of the reflector 1 engages or abuts against the peripheral edge of the casing 7. By this means, the reflector, the lamp socket and the lamp are clamped as a unit in the casing and may be readily removed, when desired. vThe usual glass or Specification of Letters Patent.

Serial No. 2,751.

lens is mounted in a ring or frame 10 which may be secured in place by means of the thumb screws 10.

The casing 7 of the headlight is mounted upon a hollow arm 11, which, in turn, is secured to a bracket 12 that is adapted to be attached to the frame of the vehicle by the bolts 14. The bracket 12 is provided with a central opening 12, through which the electrical conductor 16 may pass to the interior of the hollow arm 11. As shown in Fig. 2,-the lower end of the conductor 16 is connected to a roundel 15 carried by the bolt 14, and a second roundel 13 carried by the bolt 14 may serve as a place of connection for the conductor leading from the source of current. The upper end of the conductor 16 passes through an opening 15 formed in the casing 7 and is connected at its extremity to a roundel 17 carried by the bolt 6. The electric current, therefore, passes from the roundel 13 to the bolt 14, then through the conductor 16 to the roundel 17, and thence to the electric lamp through the bolt 6. As

shown in Fig. 1, the inner extremity of the bolt 6 has a central bore to receive the yieldingly-held contact member 18 and it is through this contact member that the current is supplied to the lamp from the bolt 6.

The casing 7 of the headlight is provided with a plurality of openings 14 to admit or discharge air from the space between the re- Hector 1 and thc casing 7. As the lower end of the arm 11 is provided with an opening 13', it is obvious that a circulation of cooling air may be maintained through said opening 13', arm 11, the space betweenpthe reflector 1, and the casing 7, and the openings 14.

In order to enable the operator of the vehicle to tell Whetheror not the lamp is burning, the casing 7 is provided with an aperture 19 and the reflector 1 is provided with an opening Q0. The aperture 19 and opening 20 are so positioned that by looking through them, the operator can see the lamp within the headlight and ascertain whether or not the lamp is burning.

Various changes may be made in the details of the construction without departing from the spirit or scope of the invention, as defined in the accompanying claims.

What I claim is:-

1. An electric headlight for automobiles and other vehicles comprising a, casing, e reiector spaced therefrom, the casing being provided with an aperture to place the space between the casing and the reflector in communication with the atmosphere, a hollow arm upon which the casing is supported,

said arm being in communication at one end with said space between the casing and reflector' and at the other end in communication with the atmosphere.

2. An electric headlight for `automobiles and other vehicles comprising a casing, a reflector spaced therefrom, the casing being provided with an aperture to place .'the space between the casing and the reflector in communication with the atmosphere, a hollow arm upon which the casing is supported, the upper end of the erm being in communication with the space between the casing and reflector and the 'lower end of said arm being bent rearwardly and in communicetion at its extremity with the atmosphere.

3. An electric headlight for automobiles and other vehicles comprising a casing, a reflector spaced therefrom, the casing being provided with an aperture to place the space between the casing and the reflector in communication with the atmosphere, a hollow arm upon which the casing is supported, Said arm communicating at one end with the atmosphere and at the other end with the space between the casing and the reflector at a point directly under the reflector. i

In testimony whereof I alix myvsignature in presence of two witnesses.
